I've run into civilians who occasionally show a lack of respect towards bassists, although in my experience they're pretty rare. I've never personally been treated badly by other musicians purely because I play bass. Quite the opposite in fact.
FWIW my long time SO is a rock guitarist. So as far as guitarists go, I can definitely say there's at least one redheaded guitarist who seems to like a certain bass player just fine despite a reputation for not suffering fools gladly.
